The City and Hackney Children's Safeguarding Board (CHCSB)

The CHSCB is the key statutory body overseeing arrangements for safeguarding children and young people across the City of London and the London Borough of Hackney.

Made up of senior leaders from a range of different organisations, the CHSCB has two basic objectives; to co-ordinate the work of agencies in safeguarding and promoting the welfare of children and young people to ensure that this work is effective.

Are you worried about a child or young person?

The Council, City and Hackney Safeguarding Children's Board and the NSPCC are working together to help residents who are worried that a child or young person is being exploited.

There are lots of reasons why a child or young person might start acting differently. But a change in behaviour could be a sign that they're at risk. Gangs, sexual exploitation and radicalisation can all be dangers for young people.

Possible signs that a child or young person is affected:

"They've started hanging around with people I don't know, and some of them are older."

"I don't know how they're affording all these new things."

"I don't understand why they've got a second mobile phone."

"They've become so intolerant of people who think different things to them."

"They've become really interested in knives and guns."

"They've been going missing overnight and skipping school - I don't know where they go."

"I can't understand why their groups of friends spend so much time in this one place."

"They're suddenly so interested in politics and foreign affairs and I don't know where they get their strong views from."

"They're always online and have become more secretive about what they're doing"

"I've noticed cuts, burns and bruises on them and I've no idea how they got them."

If you've noticed any of these signs, it doesn't mean that a child is definitely at risk. However, please talk to us about anything you've noticed that you're worried or uncertain about. We can give you free advice and support, and help you keep them safe.
